FIREPROOF WINDOW.

Application filed May 4, 1918.

provements in windows of the type wherein the frame and sash are constructed from rolled steel, in contradlstinction to structures built up from sheet metal, known as hollow sheet metal windows.

Speaking generally, the invention embodies several cooperating features among which may be mentioned window locking means associated with the top of the frame and cooperating with the top of the sash, additional locking means associated with the bottom of the sash and cooperating with the sill, improvements in the window pivots and stop and structural improvements in the window frame and sash.

More specifically, the locking mechanism, in its preferred form, is composed of a member, preferably a type of angle iron, which extends the full length of the sash, both at the top andbottom thereof, which serves to not only look the window with absolute curity, but permits of the employment of a packing between the sash and the frame,

' and, also, between the locking plates and their associated parts, whereby the window is"'also rendered practically air, water, dust or noise proof.

The improvements in the pivots and gravity stop render them particularly ehicient in rolled steel windows, and the structural changes in the frame and sash consist in the employment of shapes of special construcment of the'invention, though this specifiction, which force the air entering between the sash and the frame to follow such a tortuous path as to practically prevent any perceptible drafts.

Features of the invention, other than those adverted to, will appear from the hereinafter detailed description, taken in conjunction with the accompanying drawings and appended claims.

In the accompanying drawings I have illustrated the preferred practical embodi- Specification of Letters Patent.

Referring to the drawings, the building structure, in which the window is installed,

is designated 1, the frame, in its entirety, 2,

and the sash, in its entirety, 3,

The frame embodies the sill 4, formed of the two angle irons 4; and 4 secured together by riveting or Welding, top member 5, also of angle iron, and-the side members hereinafter described. In order to permit of the sash swinging inwardly'from the top and outwardly from the bottom, both the side members of the frame and the sash are constructed differently, in cross sections, below the window pivots than above the same. The cross sectional structure of said side members above the pivots is clearly shown in Figs. 3 and 3". Referring to the construction of the side members of the frame at this part of the window, they enibody a T-iron 6, on the inner side of which is "secured, by welding or otherwise, a 2- iron 7, relatively positioned as shown in Fig. 3, whereby a channel or groove 8 is formed on the inner side of the frame. The sash at the part of the window described embodies an angle iron 9 to which is secured a U-shaped member 10, the legs of which are of unequal length, as shown, with the short leg 11, seating in channel 8 of the frame. Moreover, intermediate the long and short legs of the U-member, there is formed a channel 12, within which one leg of angle iron 9 is seated. The construction specified results, further, in the formation of a pocket or chamber 13 between the sash and the frame, so that, as plainly appears, air endeavoring to pass into or out of the building, when the window is closed, meets with several baflles which effectually prc elude any possible draft.

In order to make the joint between the sash and the. frame still tighter than is feasible even with the baffled construction described, felt or other suitable packing 14 is employed to line channel 12, thereby making the joint not only additionally air tight, but, also, dust, water and noise proof.

Referring now to the construction of the frame and sash below the window f ame, as shown in Figs. 5 and 5 the side members of the frame embody a T-iron 15, on the inner side of which is secured what is, substantially in effect, a double Z-iron 16, or, more precisely, a Z-ir0n with a U-iron attached thereto, thereby forming the grooves or channels 17 and 18. The sides of the sash, at the parts under consideration, embody an angle iron 19, the forwardly projecting: side of which 20, seats in the channel 18 to form a tight joint. Channel 18 is preferablv lined with felt or other packing 21. U

Referring now to the locking mechanism, and particularly to the top lock, this embodies, in its preferred form, a plate 22, of substantially the same length. as the width of the sash, said plate being pivotally mounted, at its rear edge, through the pivot pins 23, at its ends, to the forwardly proecting legs on 'l -irons 6 of the frame. The front part of the locking plate 22 is hook shaped, in cross section, as shown at 2ft, so that, when in locked position, the hook portion extends downwardly so as to project over and embrace the upwardly extending member 25 of the angle iron 26, this latter iron forming the top cross piece of the sash. The rear face of member 26 is preferably lined with felt 27, as is, also, the inner face of the hook shaped portion 24 of the lockmg. member, see 28, thereby forming especially tight oints between the sash and the frame and between the lock and the sash.

Locking plate or member 22 is provided, near its center, with a forwardly projecting nose piece 29, which cooperates with a pivoted, weighted latch or catch 30, pivoted at 31, to a plate or projection 32. on the sash,

whereby the lock may be released and the sash. manually opened in the manner hereinafter described.

Referring now to the bottom look, see Figs. 1, at, 7 and 9, this embodies a locking plate 33, of substantially the same form as the top locking plate 22, said plate 33 being provided at either end with a pintle 3ft, see Figs. 1 and l, loosely mounted for pivotal movement in the side members 19 of the St sh, whereby the sash may be tilted into and out of its locking position with respect to the sill, when the sash is opened and closed, respectively. The inner face of looking plate or member 83 is lined with felt 35, and a similar lining of felt is applied to the inner face of the upstanding member 31' of the sill, thereby securing air-tight, noiseless junctures between the sash and the sill and between the locking plate and the sill.

The modes of operation of the top and bottom locking plates are substantially the same, both closing by gravity, but, as has been noted, the top locking plate is pivoted to the frame whereas the bottom locking plate is pivoted to the sash.

Projecting forwardly of the lower locking plate 33 is a nose piece 38, to which one end of the chain 39, is secured, said chain thence extending upwardly and being threaded loosely through a loop 40, connected with weighted latch piece 30, whence it extends, and is secured to a hook or catch ll on the sill, whereby the sash is retail ed in open position, see Figs. 4, 6. and 7. he chain 39 15 provided with the customary fusible link 4-2, whereby the chain is disrupted in the event of fire, and the sash automatically closed by gravity.

Referring now to the window pivot, on either side of the window, these embody an angle shaped attaching plate 43 secured to the sash and to each of which plates is affixed a pivot or trunnion n. These pivots have hearings in supports 15, secured to the outer faces of the side members of the frame. The sash is thus free to turn on these pivots.

Pivotally mounted on one of the attaching plates 43, through the medium of pivot 4:6, is a weighted gravity latch 1-7, the lower end of which, when the sash is opened, engages a stop 41:8 on the trunnion supper-t thereliiy limitin the forward, downward movement of the sash. By tilting the latch out of engagement with the stop, however, the rotary movement the window can be continued. and thereby practically reversed: i. 6., the outside of the window made accessible from the inside of the building; for cleaning, etc.

The operation of the structure described will be readily understood, but it may be briefly described as follows. When the sash is in closed or locked position, the upper and lower locking plates occupy the positions shown in Figs. 1 and 2, and in full lines, on an enlarged scale, 111 Figs. 8 and 9,'w1th the gravity catches occupying the positions shown. hen. however, it is desired to open the sash, a pull on the free or lower end of chain 39, causes the sash to tilt inwardly, and. synchronously therewith, the end of chain 39, being afiixed to nose piece 38 of the lower locking plate, tilts the latter upwardly, free from engagei'nent with the sill el, whereas the intermediate upper portion of the chain, through its loose or running engagement with the gravity latch 30, causes the latter to be thrown upwardly on its pivots, whereupon it engages the nose piece 29 of upper locking plate 22, and tilts it upwardly out of engagement with the top member 26 of the sash. The positions of the upper and lower locking plates, as well as those of the nose pieces and gravity catches associated therewith, when the sash is in open position, is clearly shown in dotted lines in Figs. 8 and 9, and in full lines in Figs. 4, 6 and 7. The sash may then be swung inwardly till the gravity latches 4C7 engage their stops, whereupon the sash is locked in open position by securing the end of the chain to hook Al, affixed to the sill. In the event of fire, fusible link 42 is disrupted whereupon the sash automatically swings into closed position.

In sashes 5 feet, or over, in width, the underwriters specifications call for the provision of two locks at the top and bottom of the window, respectively, but, as yet, no simple construction has been devised which comes within the said requirements. The structure of the present invention, however, is, manifestly, superior to that called for by the underwriters, yet it is simple and practical in construction and entirely efficient for its intended purposes.

It will be understood that the structure described may be varied in details, such as by the substitution of equivalents, and that parts of the invention may be availed of without necessarily using them all inconjunction, or employing them in the specific environment shown, all without departing from the spirit or substance of the invention as hereinbefore described, the scope of which is as broadly novel as is commensurate with the appended claims.

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent, is:

1.
